The best way to make nail polish last longer

I find natural nail polishes can thicken over time but I keep buying the Kester Black thinner over and over to get the most life out of my nail polish! It gives me so much more polish because I can use it all up!

Works great

I bought this for a different brand too coat (Holo Taco). This did the trick! My only suggestion would be to make it easier to dispense (i.e. a dropper or nozzle) as it's just a regular bottle opening and hard to transfer into a nail polish bottle, but the product itself is great.

Keeps your favourites alive

I always knew there was a thinner in existence but never saw it in the shops. This is KB thinner is exactly what you’re after for those favourite polish colours that are getting down to the last few uses. I had a red KB from at least 3 years ago and stopped using it because it was getting a bit harder to apply. Few drops of thinner and it’s good as new.
